Internet was awesome, just a stone's throw from Nana BTS. It's within the city yet away from the noise. Although its right at an intersection so if you missed it the driver needs to make a huge U-turn. So if you need to direct your taxi, just tell them its near and opposite Grand Sukhumvit hotel. Was on a business trip with some colleagues, it was a nice nook to do work, and just chill out. Bathroom was huge!
Only elevator wasn't working at some points. But staff was friendly even though they barely spoke english. Security is guaranteed.
